C or higher for DC wiring

• Use #10 AWG

(.1019” or 2.60 mm) or larger approved cables rated 75

C or higher for AC wiring

Environmental Concerns

In the event an OutBack Extreme Inverter/Charger needs to be disposed of, its aluminum casing is

easily recyclable as are any stripped out internal metal and plastic parts. All circuit boards and electronic

components should be disposed or recycled in accordance with local environmental laws.

Maintenance

• Periodically check that the battery cable lugs are tight and secure according to the recommended

torque settings (60-inch pounds/6.77 Nm).

• Brush o excessive dust from the inverter/charger as needed.

• Check that fasterners securing the inverter/charger to its mounting surface are tight.

If the OBX-IC is not inverting:

• Verify the DC battery voltage at the inverter/charger terminals

• Verify a lack of AC output

• Call OutBack Technical Support for further assistance.

Storage

Store each inverter/charger unit in a cool, dry area.

Parts Included

• One OutBack Extreme Series Inverter/Charger (OBX-IC)

• One “WARNING ELECTRICAL SHOCK” sticker to place on the exterior of the OBX-IC mounting

location

• One packet of silicone grease to protect CAT 5e communication cable connections

• One installation manual

• One Turbo Kit

NOTE: Due to the variety of installation options available to a user, mounting hardware is not included.

Any chosen fasteners must be adequate to support the weight of the OBX-IC and no fewer than four

fasterners, one per corner, should be used for a safe installation.

Dimensions

• Each OBX-IC measures 8.25” x 16.25” x 13” (20.95 cm x 41.27 cm x 33.02 cm)

• Depending on the model, an inverter/charger weighs between 56 (25.4 kg) and 62.6 lbs (28.39 kg).

IMPORTANT SAFETY INSTRUCTIONS/SAVE THESE INSTRUCTIONS

Read all instructions and cautionary markings on the inverter/charger, the batteries and all appropriate

sections of this installation and user manual as well as other component manuals before using the

system.

Be cautious around electricity, electrical components, and batteries. Shocks, burns, injury, and even

death can occur if an installer comes in contact with electricity.

Install all components and wiring according to national and local electrical and building codes. This

includes:

• Submitting a plan to the local building department

• Passing inspection

OutBack Power Systems cannot be responsible for system failure, damages, or injury resulting from

improper installation of their products.

Use only the recommended DC and AC wire sizes or greater. Be sure all wires are in good condition.

Install the inverter/charger in a dry location, preferably indoors.

• Install the inverter/charger in a shaded area out of direct sun

light for best operation.

• For installations where the inverter/charger may be exposed to water spray, a sealed inverter/

charger must be used and mounted either with the base down (shelf mounting) or with the AC

wiring compartment facing down (wall mounting).

• If mounted with the base down, water cannot be allowed to accumulate around the inverter/

charger’s base. There is a drainage system on the base of the inverter/charger to dispel

condensation.

• If submerged, water can enter this drain and cause failure.

INITIAL INSPECTION

Your inverter/charger is stoutly packaged for secure shipping. Please inspect the packaging and com-

ponent for damage or exposure to water prior to intallation. Never power up a damaged OBX-IC.

READ FIRST!

Design the battery enclosure to prevent accumulation and concentration of hydrogen gas in “pockets”

at the top of the enclosure. Vent the battery compartment from the highest point to the outside. A

sloped lid can also be used to direct the  ow of hydrogen to the vent opening.

CAUTION

To reduce risk of injury, charge only deep-cycle lead acid, lead antimony, lead calcium, gel cell or

absorbed glass mat type rechargeable batteries. Other types of batteries may burst, causing personal

injury and damage. Never charge a frozen battery.

PERSONAL PRECAUTIONS

• Someone should be within range of your voice to come to your aid if needed.

• Keep plenty of fresh water and soap nearby in case battery acid contacts skin, clothing, or eyes.

• Wear complete eye protection. Avoid touching eyes while working near batteries. Wash your

hands with soap and warm water when done.

• If battery acid contacts skin or clothing, wash immediately with soap and water. If acid enters

an eye,  ood the eye with cool running water at once for at least 15 minutes and get medical

attention immediately following.

• Baking soda neutralizes lead acid battery electrolyte. Keep a supply on hand in the battery area.

• NEVER smoke or allow a spark or  ame in vicinity of a battery or generator.

• Be extra cautious to reduce the risk of dropping a metal tool onto batteries. It could short-circuit

the batteries or other electrical parts and can result in  re or explosion.

• Remove personal metal items such as rings, bracelets, necklaces, and watches when working with

a battery or other electrical current. A battery can produce a short circuit current high enough to

weld a ring or the like to metal, causing severe burns.

WARNING: WORKING NEAR LEAD ACID BATTERIES CAN BE DANGEROUS. BATTERIES

GENERATE EXPLOSIVE GASES DURING NORMAL OPERATION.

• Never install extra washers between the terminal

mounting surface and the battery cable lug—

the connection must be direct and secure.

• Always install breakers or fuses within the

positive battery cable.

• Torque 2/0, 4/0, or larger NEC approved cables

rated 75

C or higher to 60-inch pounds/6.77Nm.

SYSTEM PROTECTION

An OutBack Extreme Series Inverter/Charger is part of an electrical system that protects:

• You

• The wires

• The components

• The devices served by the electrical system

Each OBX-IC must be part of a permanently grounded electrical system (see page 8). Grounding

protects people and equipment from electrical shock. Grounding must be done according to local and

national electrical codes.

OutBack circuit breakers protect wiring by limiting the amount of current entering a system. All wired

electrical systems require circuit breakers or fuses for protection.

OutBack o ers both breakers and fuses for over-current protection. If they are provided by other

vendors, they must be properly rated.

AC WIRING COMPARTMENT BOARD

• AC HOT OUT supplies power to the loads.

• AC NEUTRAL OUT acts as neutral leg for loads

supplied by the OBX-IC and is common with the

AC NEUTRAL IN.

• CHASSIS GROUND connections are common

and act as grounds for both the incoming and

outgoing AC circuits.

• (AC) NEUTRAL/GROUND BOND is connected

to the chassis ground terminal with a removable

jumper.

• AC NEUTRAL IN acts as the neutral leg for AC

power supplied by either the grid or a generator

to the OBX-IC.

• AC HOT IN connects incoming AC from the grid

or a generator to the OBX-IC. This AC is used to

run loads and recharge batteries.

connections to the OBX-IC using set screws

AC AND DC GROUNDING REQUIREMENTS

• Connect only to a grounded, permanent wiring system. Ensure there is only one AC and DC

neutral-ground connection in the system at any time.

• If the system has a generator, disconnect its neutral-ground connection if present.

• For all installations, the negative battery conductor should be bonded to the grounding system at

one (and only one) point in the system.

• The OBX-IC should never be positive grounded.

The equipment ground on each is marked with this symbol:

PARTS AND ACCESSORIES

BATTERY TERMINAL COVERS

• The caps are made of sti plastic with a snap-on

design; remove them carefully using a  at-blade

screwdriver inserted into the slots on the sides of

each cover.

• Always keep the battery terminal covers installed.

AC CONDUIT PLATE*

• AC conduit connects to the AC Conduit Plate for

installations which do not utilize an ACA.

MOUNTING

• The OutBack Extreme Series Inverter/Charger is approved for indoor or enclosed protected mounting only.

• An OBX-IC weighs approximately 62 lbs (28.2 kg) and must be secured with appropriate fasteners to a sturdy

mounting surface capable of supporting its weight. It is easier for two people to install due to the OBX-IC’s

weight.

• The OBX-IC can be mounted in any position, but they perform better in locations o ering plenty of air

circulation.

• Due to the variance in other mounting methods, OutBack only endorses the use of FLEXware or previous

versions of its mounting plate for installing the OBX-IC and associated system components using M6 X 20mm

machine screws, one per corner. Follow the instruction manual that comes with each mounting system.

• If mounting the OBX-IC on other surfaces such as plywood, wall studs, or masonry, use appropriate fasteners

to support approximately its weight. OutBack cannot be responsible for damage to the inverter/charger if it is

attached with inadequate fasteners.

• Install and secure each OBX before attaching any wiring.

Jumper

Follow these steps to wire the OBX-IC to your system:

1. Shut all AC breakers o or remove any fuses before connecting any wiring.

2. Shut o all DC breakers, including, if present, any PV breakers.

3. With all power o , run lengths of 10 AWG

(.1019” or 2.60 mm diameter) wire between the AC Wiring

Compartment Board AC out terminals and a 30 amp over current protection circuit breaker

depending on the OBX-IC model. The breaker should be installed inside of a metal enclosure, such

as OutBack’s FLEXware series or an existing panel.

4. With the over current protection connected, run lengths of 10 AWG

(.1019” or 2.60 mm diameter) wire

between the AC Wiring Compartment Board AC IN terminals and the AC input breaker. The breaker

should be installed inside of a metal enclosure, such as the FLEXware series or an existing panel.

The AC input hot conductor must be supplied through a 30 amp maximum AC branch rated circuit

breaker.

• Use crimped and sealed copper ring terminal lugs with 5/16” (8 mm) hole or compression-type lug

to connect battery cables to DC terminals. Soldered cable lugs are also acceptable.

• Use recommended cable sizes (see page 29) to reduce losses and ensure high performance of OBX

(smaller cables can reduce performance and possibly damage the unit).

• Keep cables together (e.g., using a tie-wrap) as much as possible.

• Ensure cables pass through the same knockout and conduit  ttings to allow inductive currents to

cancel.

WIRE CONNECTIONS

NOTE: A system’s individual voltage requirements (120 single phase, 120/240 split phase, or 3-phase)

as well as how each OBX-IC is to function all determine how the OBX-ICs are wired. Each OBX-IC must

be wired to the logical leg or phase of the system. Each OBX-IC must be programmed or “stacked”

according to this phase. Please see the FX and VFX Series Inverter/Charger Programming Manual before

connecting any wires to or from the OBX-IC.

Prior to installing an ON/OFF switch, if the OBX-IC’s AC output is o , check that the

jumper is present and well-connected before installing a switch. You want to con rm the

system is in good working order.

Should you decide to install an OutBack MATE at a later date, bear in mind the installed

switch overrides the control provided by the MATE if the switch is set to OFF. If the switch

is set to ON, the MATE will function normally and control the inverter(s).

• When a system is ordered with a MATE, the MATE handles all OBX-IC ON/OFF functions (unless an

optional ON/OFF switch is installed).

AUXILIARY OUTPUT ( AUX + / AUX - )

The Auxiliary output system uses the AUX + and AUX – terminals. It is programmed through the MATE

to do a variety of tasks:

• The default use for these terminals drives the OutBack Turbo for external cooling.

NOTE: These terminals should not be connected to any type of DC load greater than 0.7 amps.

• The OBX-IC includes internal electronic over-current protection for the AUX 12VDC output circuit

which auto resets if it is short-circuited. No additional fuses are required.

• For automatic or advanced generator start functions, the Auxiliary Output can drive a 12V relay coil

for the two-wire starting circuitry of a generator. OutBack recommends a good quality gold-plated

relay.

NOTE: OutBack Power Systems does not support three-wire start generators; however, a three-wire

to two-wire conversion kit is available from an electronic control manufacturer such as Atkinson

Electronics (www.atkinsonelectronics.com).

SERIES DUAL OBX-IC CONFIGURATION

• This system can continuously power up to 5kW of AC loads depending on the ambient tempera-

ture.

• A dual OBX-IC system requires 30A two-pole AC input breakers.

NOTE:

• Stacking two OBX-ICs in series means there are OBX-ICs directly connected to two separate 120VAC

output legs. These legs produce 240VAC between them (the series portion) as the two inverters

are “out of phase” with respect to each other. This allows all of the OBX-ICs to power either of the

120VAC output legs (the parallel portion).

• When the OBX-ICs are connected in series for 120/240VAC:

• The FW-X240 Auto Transformer can be connected to the AC output; both OBX-ICs power

capacity is then available on either 120VAC output circuit.

• This allows higher e ciency and better performance as heavy 120VAC loads are powered

by both OBX-ICs.

• The FW-X240 Auto Transformer also allows the Master OBX-IC to power loads on either

120VAC output circuit with the Slave OBX-IC o , reducing idle power consumption and

improving system e ciency.

• The Slave OBX-IC must be programmed through the MATE as a “Classic Slave’” (series stacking, no

FW-X240 Auto Transformer) or as “OB Slave L2” (series/parallel stacking, FW-X240 included).

The OBX-IC connected to Port 01 of the HUB is always the Master (1-2ph MASTER)
